@herve,
The wordpress date is well activated and works very well with the forum, but not with the poll.
ok, we'll check and back to you asap.
The phrase "Voter(s): " does not exist, and if I add it, what should I write: "Voter(s):" or "Voter(s): %d" ?
No need to add it manually, just navigate to Dashboard > Forums > Dashboard admin page, click on the "Rebuild Phrases" button, then search the phrase,
